Floor concrete crack repairing construction process
The invention discloses a floor concrete crack repairing construction process which comprises the following steps: S1, drilling a hole in the end part of a crack to limit the expansion of the crack; s2, polishing the V-shaped groove along the crack; s3, a preset area extending outwards of the crack is polished; s4, a glue injection nozzle is assembled in the V-shaped groove and arranged in a straddle mode, strong concrete glue is smeared along the crack, and the surface is scraped to be flat; s5, opening a glue injection nozzle, injecting glue, and blocking the glue injection nozzle when the slurry flows out; s6, after the glue injection liquid is solidified, a glue injection nozzle is dismantled, strong concrete glue is filled, and after the strength requirement is met, the surface of the floor slab is roughly polished; s7, preparing epoxy resin glue, uniformly coating the epoxy resin glue on the crack of the floor slab, and then pasting the carbon fiber cloth on the corresponding position; and S8, after the transverse carbon fiber cloth is pasted and dried, scraping the resin adhesive, and pasting the longitudinal carbon fiber cloth. The method has the beneficial effects that the repairing and reinforcing efficiency of the cracks of the concrete floor slab is improved, and the method has high practicability, good economic benefits and application prospects.
本发明公开了一种楼板混凝土裂缝修补施工工艺，该工艺包括：S1、在裂缝的端部钻孔，限制裂缝扩大；S2、沿裂缝打磨V型槽；S3、在裂缝向外延伸预设区域打磨；S4、将注胶嘴装配在V型槽内，并骑缝布置，沿裂缝涂抹强砼胶胶泥，并进行表面刮平；S5、打开注胶嘴，并注胶，流出浆液时对注胶嘴进行封堵；S6、待注胶液凝固后，拆除注胶嘴并填充强砼胶胶泥，达到强度要求后，对楼板表面进行粗打磨；S7、配制环氧树脂胶，将其均匀地涂在楼板裂缝处，随即把碳纤维布粘贴在对应位置；S8、待横向碳纤维布粘贴干燥后，刮涂树脂胶，粘贴纵向碳纤维布。本申请的有益效果是：提高混凝土楼板裂缝的修补加固效率，具有较强的实用性、良好的经济效益及应用前景。
